| Abstract: | Combined with the concrete project example,the author introduces the entrance construction scheme of the shallow big cross-section tunnel,analyzes the process principle and the concrete construction procedures of the micro-bench method,draws a conclusion that the micro-bench method can effectively control the overbreak and reduce the damage to the surrounding rock,to popularize the application of the micro-bench method in the shallow big cross-section tunnel. |
